At present, there are quite literally dozens of conglomerates in India, and out of these, many are the significant ones that are not just popular in the business scene, but the general public also knows the true scale of the companies or business groups. But for those who don’t know what really a Conglomerate is, well, it is just a group of different companies working not just in one nation but in different countries as well. Thankfully, many of India’s conglomerates are among the fastest growing ones in the entire world, and of course, they’re doing super good right here in the homeland as well. So, it is about time that we talk about these Top 10 Biggest Conglomerate Companies in India. Here we go.
1. Reliance Industries Limited (RIL)

See, when searching for the term about the biggest business groups or conglomerates in India, you must have already thought it through that Reliance Industries would be at the top of this list, and that is precisely the case. In fact, they have been holding the top spot for several years now, one after the other. Like, despite the fluctuations in its market capitalization, mainly it is around ₹21 trillion as of mid-December 2025, Reliance is the company that holds the highest value in India for the longest time.
2. Tata Group

And just in the runner-up position, see Tata Group is the one and surely among the most trusted names in the country for decades now. The group, which spans over 30 companies, is said to be worth somewhere between ₹18 and 20 trillion in 2025. TCS by itself is a major factor in the group’s valuation, whereas the likes of Tata Motors, Tata Steel, and Tata Power are the ones that make the group solid from an industrial perspective. It is not just the scale of this conglomerate, nah, it is their visionary thinking and the trust that they have built up that makes them unique and worthy of listing this high up in the ranking.
3. HDFC Group

HDFC? Well, yes, it is now known as a conglomerate, like the merger of HDFC Ltd and HDFC Bank changed the entire landscape of India’s financial sector and that is why the HDFC Group is ranked at number three on this list. And talking about numbers, see, HDFC is presently the biggest private banking institution in India with a valuation of more than ₹16 trillion. The group’s power is in its three-core sectors, banking, insurance, and asset management, well at least that’s the case as of 2025. HDFC does not complicate things like diversified industrial conglomerates, but just keeps it simple and extremely effective.
4. Adani Group

Well, just a few years ago, you must have seen some big attacks and allegations made by foreign companies on the Adani Group, which turned out to be false and baseless. Though that was a big hit for the conglomerate, they’re back on track once again, and that’s why we have listed them at number four here. Adani, with a valuation of more than ₹12 trillion, has revived investor sentiment by implementing growth that is energy and infrastructure-driven. And no doubt, right now, as of 2025, the group is a major influencer in India’s economic backbone, from ports and logistics to power and renewable energy.
5. Bajaj Group

And going down just one spot, see, the Bajaj Group is a model that shows how minimal diversification is enough to become a strong conglomerate of one’s business. This is the reason why we have ranked the Bajaj Group as the fifth most valuable company. With the total market value of approximately ₹9 to 10 trillion, Bajaj has its main operations in the areas of finance and automobiles. And just so you know, India is the home to two outstanding financial brands, such as Bajaj Finance and Bajaj Finserv, while Bajaj Auto is the leader in the global two-wheeler market of the next eleven countries.
6. Aditya Birla Group

And then, well, the biggest thing that differentiates the Aditya Birla Group from the rest of the business scene is its robust worldwide presence along with the fusion of traditional and modern Indian industries. For this reason, it ranks 6th on our list. And? Oh, the conglomerate which is estimated to be worth between 7 and 8 trillion rupees, is involved in the areas of metals, cement, textiles, telecom, and financial services.
7. Larsen & Toubro (L&T Group)

It is pretty much true that very scarcely are there companies that can rival L&T in India in terms of engineering and infrastructure. Consequently, it is L&T Group that occupies the 7th position in our ranking. With a worth of about ₹5 to 6 trillion, L&T is super important in the process of constructing India’s infrastructure, which includes the likes of highways, power plants, and defense projects all over the country.
8. Mahindra Group

You know, one of the reasons that the Mahindra Group climbed up to number eight in the ranking is the company’s commitment to be in industries that are oriented towards the future, pretty much. Just to give you an idea of that, see, the value of Mahindra, which is spread over sectors like automobiles, IT, finance, agriculture, and renewable energy, is estimated to be approximately ₹5 to ₹6 trillion.
9. JSW Group

Without a single doubt in the fact that JSW Group, in a subtle way, expanded itself to be one of the major industrial conglomerates in India, which is the reason it is ranked at the ninth position. JSW, with a worth of ₹4 to 5 trillion, is heavily dependent on steel, energy, cement, and infrastructure sectors; at least that’s the case in 2025 for them.
10. Godrej Group

Oh, and finishing this list very well, see, at number ten on our list is the Godrej Group, one of the oldest and most illustrious business houses in India. Valued at around ₹3 to 4 trillion, Godrej is diversified across FMCG, real estate, appliances, and engineering. Godrej Consumer Products continues to be a very popular brand, whereas Godrej Properties has created a solid position in the real estate sector so far.
Conclusion
That is about it. See, we can keep on talking about these big conglomerates all day long, but for a brief introduction, this list is enough. And sure enough, there are many more conglomerates to talk about, but for the sake of keeping it a top 10 list, let’s just end things here.
